HEEL CONSTRUCTION.

Specification of Letters Patent.

Application filed au ust '2, 1917. Serial No. 184,027.

To all whom it may concern:

Be it known that we, NICHOLAS H. Mono- ZOWICZ and JOHN R. A. FARR, bothcitizens of the United States, and residents, respectively, of theboroughs of Bellevue and Ben Avon, in the county of Allegheny and Stateof Pennsylvania, have invented or discovered certain new and usefulImprovements in Heel Construction, of which the following is aspecification.

Our invention consists in a certain new and useful improvement in rubberheels for boots and shoes, and more particularly comprises improvedmeans for attaching to a rubber heel an outer tread or wearing surfaceof leather or some other wear resisting material.

The use of a rubber heel where the resilient material forms the treadsurface which comes into contact with the ground is attended by thedanger of slipping, especially where the heel is worn by use, and alsothe tendency is to aggravate fallen arch trouble. It has been recognizedthat the ideal heel would be one with an outer tread surface of leatherand a resilient rubber body portion interposed between the outer treadand the permanent heel base of the shoe, but great difiiculty has beenmet in properly attaching the leather tread to the rubber in such amanner that it will not easily come 0E and at the same time theresiliency of the heel wil7lv not be destroyed or materially impaired.

e ing the rubber heel with members of rigid material, such as wood,whose heads or enlarged portions are seated in recesses in the innerface of the rubber, said recesses being of sufficient depth to preventthe members coming into contact with the heel base of the shoe when therubber is compressed, and the members are provided with shanks orprojecting portions extending through holes in the rubber to theexterior surface of the same and to which the leather tread is securedby screws or nails.

In the accompanying drawings, Figure 1 is a perspective showing ourimproved heel structure before it is applied'to the shoe; Fig. 2 is asection taken along the line II-II inFig. 1, but showing the heelstructure attached to the heel base of a shoe; Fig. 3 is a top plan viewof a modified form of our heel structure; Fig. 4 is a sectional view ofthe same taken along the line overcome these difiiculties by providventthe heads of the members D coming IV-IV 'in Fig. 3; Fig. 5 is anelevation of the form of attaching member shown used in Figs. 1 and 2for securing the leather tread to the rubber heel, and Fig. 6 is asimilar View of the form of attaching member shown used in Figs. 3 and4.

The following is a detailed description of the drawings, reference beingfirst had to Figs. 1, 2 and 5.

A represents a leather tread or lift which is to be used as the portionof the heel structure which comes in contact with the ground inwalking.B is the rubber portion of the heel, and C is the leather base for theheel which'is permanently attached to the body of the shoe.

D represents members of wood or other rigid material whose enlargedbodies or heads are seated in recesses 1 sunk in the upper surface ofthe rubber heel B and whose shanks extend through smaller holes 2 to theouter surface of the rubber heel B. The leather tread A is attached tothe outer surface of the rubber heel B by means of screws or nails 3which are driven through the leather tread into the outer ends of saidshanks of the members D. The shanks are preferably short enough torequire a slight compression of the rubber to bring the tread up snugagainst the face of the rubber and to hold the heads ofthe members D inthe bottoms of the recesses out of all possible contact with the solidheel base C.

The recesses l are deep enough to preinto contact with the heel base Cwhen the rubber is compressed by the action of the shoe in being worn.

The heel structure, comprising the tread and rubber heel may be attachedto the shoe y the usual nails 4 which are driven through annular washers5 embedded in the rubber, holes 6 being provided leading down throughthe tread and rubber to said washers so that the nails can beconveniently driven into place.

In Figs. 3, 4 and 6, we show substituted for the members D, the bridgemembers D comprised of two or more studs 7 and a connecting bridge orweb 8. The bridge 8 occupies a relatively deep channel 9 sunk in theinner surface of the rubber heel while the studs 7 extend through holes10 to the outer surface of the rubber heel where the leather tread isattached by the screws 3.

leather is found It is evident that the leather tread provides a flat,firm surface and is securely attachedto the rubber heel so that a firmstand will be obtained by the wearer without Wabbling, and at the sametime the resiliency is not impaired for therecan be no contact betweenthe members D or D and the :heel b'as'e C. The members cannot be pulledthrough the rubber so that the leather tread will not be torn off aslong as the screws or nails 3 remain in place. The leather tread may beremoved anda new one put in.;place When Worn out.

WVe prefer to make our attaching members 7 D or D of wood, but metal orother suitable rigid or semi-rigid material may be substituted theoutwardlyprotruding portions of said members being in such casepreferably provided with threaded holes for g the application of thescrews 8. v V g Although for vgeneral use a tread of to be the mostsuitable, it

, will be understood that a tread ofmetal or any other suitable materialmay be substituted, as. the particular need may dictate.

'What we desire to claim is 2- 1. A heel structure for a boot or shoecomprising a body of resilient material adapted to be attached to theheel base of the boot or shoeand provided with recesses sunken inltsinner surface and holes extending from said, recesses t0 the outersurface of sand body, .members of rigid material having enlargedportionsseated in said recesses out of contact with said heel base andreducedportions which extend through said' holes tothe outer 'surt'aceof said body and a tread member of non-resilient materialabuttingagainst the outer ends of said membersiand rigidly attachedthereto, substantially as and for the purposes set I forth.

Copies of this, patent may be obtainedfor 2. A heel structure for bootor shoe comprising a body of resilient material adapted to be attachedto the heel base of the boot or shoe and provided with a pluralposes setforth.

3. A heel structure for .a boot or-shoe comprising a body of resilientmaterial adapted to be attached to the heel base-o t a boot orshoe andprovidedwithan aperture extending entirely through the same, a rigid;

member arrangedwithin said apertureand extending therethrough, and atread member abutting against oneend of. the rigid member and rigidlyattached thereto.

LA heel. tructure for a boot on sh'oe comprising a body. of resilientmaterial adapted to be attached to the heel base of the boot or shoe andprovidedywith an opening of stepped formation extending entirely throughsaid'body, a'rigid member having; T

an enlarged head portion and-a reduced end portion arranged within theopening in the body and extendingtherethrough, and a tread member of1nonresilient material abutting against the reduced end portion of; saidrigid member and rigidly attached V thereto.-.
